Barbiturates Spectra from .spc example files A time series of mass spectra in a list of hyperSpec objects.
Barbiturates Spectra from .spc example files A time series of mass spectra in a list of hyperSpec objects.
The data sets consists of 286 spectra. They are the result of importing the BARBITUATES.SPC example data from Thermo Galactic's spc file format specification.
